LEDs on eBay?

My brother and I recently made an eBay account, and we were just browsing through everything and we came across many LEDs. Most of the LEDs in bulk that I saw were from China or Hong Kong. I am just curious if anyone knows how reliable, safe, and if I would be getting my money's worth. I did buy some from besthongkong.com, and those came, but I am a little skeptical about these guys on eBay. Any suggestions?

LEDs from ebay? Answered

Is ebay a reliable source of LEDs? I bought a 3 watt LED off there once (http://cgi.ebay.com.au/3-X-POCKET-LUXEON-3-WATT-LED-TORCH-FLASHLIGHT-LIGHT-3W-/320514643442) and it had kinda poor performance...but I don't know whether it was because the torch itself was poor or if the fact that buying it from ebay was what made it bad. Any how, I'm looking for a 1 - 3 watt LED, and a (narrow beam) lens for it, and was wondering where I could get it all for under $10 (AU). WOuld ebay be a reliable choice?

An Opps Purchase on Ebay Is it Salvageable?

So i have an 1998 dodge ram 1500 i purchase with no power options at all so i got power window regulators and replaced the door panels and bam I've got power windows. and since the door panels had lock buttons i bought some cheap 12v actuators off eBay and wired them up and bam. power locks.. THEN in all my creativity i was like i'll just buy an RF 4 channel kit and make it key-less. so i ordered this kit not realizing what type it was http://www.ebay.com/itm/320783435624?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649#ht_2920wt_1185 to summarize this kit requires you press one button to activate the a channel and press a second button to disable the active channel.. not at all what i was looking for.  Is there any way i can convert the kit i've already paid for into a momentary style. so as long as i'm holding the channel button down its active. ????  here are all the chip/ component numbers. 4x SRA-12VDC-CL 1x  SC2272-L4 - BD25D5D1 1x 9530FH~~~~~~ unreadable some residue on the chip a few caps a few resistors and an LED..  anyone think this is doable or should i just shelf it and get a diff kit?

How blatant is blatantly stealing ideas from ebay? Answered

Hey, I was looking for a way to build my own trolling motor on google the other day. The only real contender I found was a guy on ebay selling $4 guide on how to turn a whipper-snipper into one. My dad just bought a new electric one, so we have one sitting in the shed awaiting a new spark plug. I plan to take this, stick blades on the end and stick it in the water to see if it runs (the idea of which I took from the ebay auction) The problem here is that I was considering instructabling my progress. I havn't purchased the guide, so I wouldn't be copying his work, however I would be giving my own 2 cents on how to do something he thought of, and would be possibly denying him of his money. In a sense, I would be stealing copyrighted material and giving it for free, which I was going to do until I realised no one else mentions it on the net and he has seemingly actually invented this (which I'm not going to take from him). As of now, I'm not planning to make the 'ible, i was jsut wondering what you guys thought of this.

Where can I find a free Ebay sales map (similar to mystoremaps)? Pro Membership to the first good answer!

I recently decided to try out mystoremaps on Ebay.  It is pretty easy to use, but I don't like that the free version only includes a map of North America.  I have quite a bit of international sales, so I want something that shows all of them.  I would rather have something that can be updated easily too. Is there a free map tool that works in a similar fashion?  I really just want a map with a lot of red dots on it to mark where each sale has taken place.  I think mystoremaps has a pretty easy system set up for this task.  I just do not want to pay a monthly fee to show other continents. Here is one of my auctions so you can see what it looks like.  The map is at the bottom of the item description. Like I said in the title, the first good answer will get a code to upgrade to a Pro Member on Instructables.

Are these power supplies good?

The cheap bare metal power supplies from ebay or other sides have been reviewed many times on youtube and people have found that they are actually decent. But I cannot find any reviews of the sealed plastic kind of power supplies. The "bare metal" ones I am talking about look like this, and the "sealed plastic" ones look like this and this. Edit: None of your replies answer my question. I am not asking which one I should choose, I am asking if the plastic ones are just as decent as the metal ones. There are a few reviews of the metal ones, and people have found that they are actually quite decent. Here are some: https://www.youtube.com/watch?v=vwFrP7uK5lM https://www.youtube.com/watch?v=71NWT5vrbk8 But I cannot find any reviews of the plastic ones, so I don't know if they are just as good.

Is it practical to repair the damaged CDI or get one from eBay?

The Honda VT 250F CDI was Damaged 3 years ago and the owner left the motorcycle lying about until i found it.  There could be more issues other than the CDI since the motor has been sitting for quite a while, so I'm trying to figure out practical ways on how to fix those without spending too much since my budget is limited. I'm a total noob and have no background in motorcycle mechanics at all, just some slight electronics back in high school ( I tend to heavily rely on my circuit board manual back then). Perhaps someone here can tell me how I should approach this problem and maybe share some knowledge in fixing the CDI first before I carry on opening the machine and start tinkering. -what should I look for in the circuit board? -what tools should I use? -can someone provide me a copy of the CDI manual/layout for a Honda VT 250 F? cheers

Im starting an ebay gadget store. what are some cool fun things to sell?

Well technically ive already started, but now, ive made enough profits to begin expanding. At the moment i sell 70mw green laser modules (not pointer pens), carbon graphite rods 5/7/10mm wide at any length and from time to time i try and get rid off my liquid a$$ stink spray, though people tend not to buy that as postage is $6, and lastly long range, but very cheap, 433mhz receiver transmitter pairs . All of this , from within australia, i plan on selling things which are awsome, as well as generally inaccessible by many australians. Currently i intent to buy up 6v spark gap ignitors , identical to those on sparkfun, different coloured laser modules, titanium to weld to my MMO anode mesht cuts, more wireless receiver/transmitter pairs, though, this time, toggle/momentary ones, currently my ones are latching, i plan on buying small shockers, and lastly, Nitrates, Aluminium powder, sulfur, and all those chems which are so hard to find in australia. Also, i will start buying more, and in larger amounts, thermochromic pigment. I also plan on building DC-DC HV converters, for charging coil gun capacitors, (based on the instructable of the same name, once i get permission to use the schematic to base my design off to sell), small shocker modules (to make taser things from), Various oscillators, like flyback ones, 3D printing services and 1W regulated 808nm burner modules. Now, ever since i discovered the spark gap ignitor wholesaler, ive been thinking, "what else could i sell thats awsome and hard to come by?", but legal too, this is ebay after all. I would really like some help in finding things which arent especially expensive or big (im not buying stuff which costs like $100 a peice), but also things you would like to see sold in your local gadget stores. Really, just anything in this general catagory, stuff which is really awsome or very hard to get, either in australia or anywhere, but not illegal. like novelty gadgets, or things which do amazing things, such as mini spy cam bugs or something. I really need help, i know what kind of things I LIKE, and want, but not what others like and want. please help me out!

I don't need a laser pointer, because I already have my own circuit set up and stuff. Any thoughts?

What are the specs on this ancient RAM?

 I would like to replace the two 64 MB modules in an ancient computer with two 256MB modules. Unfortunately, Linux was unable to report a manufacturer or model for the motherboard (only that it has a 950Mhz Duron and mostly SiS onboard components.) Even that report is suspect, as it said there are four memory slots when in fact there are two. So, take a look at this photo of three sticks of memory which worked successfully in the machine. What exactly are their specifications? Then, look at the specifications in this Ebay ad.  Is it fully compatible (assuming the computer can handle 512MB)? Update: Apparently the seller who I originally linked to is a scammer. I'll reference a more legit looking Ebay seller instead.
